Vishay Intertechnology 5 W Axial Silicone Cemented, Fusible Wirewound Safety Resistor Offers Surge Voltage Capability Up to 6 kV
For Energy Meters, Home Appliances, and Power Supplies, Device Features Fusing Time of < 45 s for 100 W Overload
MALVERN, Pa. - Jan. 15, 2014 - Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new 5 W axial silicone cemented, fusible wirewound safety resistor that is the industry's first designed to ensure safe and silent fusing operation during overload conditions, while offering surge voltage withstanding capability up to 6 kV (1.2 µs / 50 µs). For electric appliances, energy meters, and power supplies, the Vishay Draloric AC05..CS combines a fusing time of < 45 s for a 100 W overload with a special non- flammable silicone cement coating for immediate interruption without flame and explosion when AC mains voltage (230 VAC) is applied.
UL1412 safety approval for the AC05..CS has been initiated and is expected by February 2014. In addition to fusing "without a bang," the safety resistor acts as an inrush current limiting resistor during normal operation. The device's specially developed non-flammable silicone cement lacquer coating allows designers to meet safety requirements more easily, while eliminating the need to utilize additional fuses in series with the input resistor.
The AC05..CS provides a power rating of 5 W at an ambient temperature of 40°C and 4.5 W at 70°C. The RoHS-compliant device offers resistance from 10
